nrzno, a subject of the King of Sweden, and

residing at Stockholm, Sweden, have invented certain new and usefulImprovements in Feed Devices for-Centrifugal Separators; and I do herebydeclare the following to'b'e a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertams to make and use the same, 'reference'being had to theaccompanying drawings, and to let ters or figures of reference markedthereon, which form a part of thisspecifieation.

In centrifugal machines for separating milk and cream it is usual totryto arrange the supply of the whole milk in such a man-' ner, that itneed not pass the cream layer for the purpose of preventing remingling.To. 8,118,111 this ObJGCt, plates have, among other things, been used,said plates having holes lying in rows, and arran ed between the outerand the inner edge of the plate, the

- whole milk being fed into the spaces between the plates of the linerthrough said rows of holes. It is quite advantageous to use bowls inwhich the bottom of the bowl. isdra vn up into the bowl to allow thetopl'iearing to be lifted up, thus saving space and attaining a steadierrunning bowl. l

The object of this invention is to produce a device, which. enables theus.- 0 plates with holes therein in bowls in which the bottom of thebowl is drawn up into the' bowl and to main ain the present simplicityof the ditt'erent parts of the bowl.

The lIHIMOVOInQHl is shown on the annexed drawing. wherein Figure 1shows a vent ritugal how] in longitudinal. section, Fig. 2 the ven ralfeed pipe in section on line .\.----ll and Fig. 3 a inoditied form ofthe ventral feed pipe.- I

o de ignah-as the central feed pipe, b the norm. rthe plates and rl thespindle of the howl. The whole milk enters at f and'runs down into achamber y, arrz'lnged above the spindle, whence channels h lead down tothe opening 1'. which correspond. to the holes in the plates. Thechannels it do not take up the whole periphery of the central feed pipe,but leave p:r-. gr-s: between them,- through which the cream can ascendalong the cen- Iral fowl pipe (.1. to the discharge opening Z. Bydividing in this manner the space between the disks and the central feedpipe into separate compartments, lying side by side, or which some servefor leadmg down the whole milk and the others for leading up the cream,it will be possible to place in the space, which must always be leftbetween the central, fee i pipe and the plates, all thuchannels whichare necessary for the streaming of the liquid. j

Fig. 3 shows a modified form of the above mentioned device, consistingtherein, that the channelsior the whole milk are 0 en on the. one or onboth sides, but so that t ere is formed a part, whlcb is cup shapedinwardly, wherein the milk during its passage downward, is retained onaccount of the centrifugal force. The object ofthe open channels is tofacilitate the cleansing.

Claims:

1.- In acentrifugal n'rilk so arator, in comoination, abowl, superposecplates therein provided-with orifices therethrough between their innerand outer ends, a central feed pipe, channelsleading therefrom at apoint above the inner edge of the bottom plate and terminating belowsaid plates and in line with said orifices.

2. In a centrifugal milk separator, in combination, a bowl, superposedplates therein provided with orifices therethrough between their innerand outer ends,"a central feed pipe, channels leading therefrom at apoint above the innerv edge of the bottom late and terminating belowsaid )lates an in line with said orifices, said channels having an openside.

3. In a centrifugal milk se arator, in com binatiou, a bowl, superposecplates therein provided with orifices therethrough between their innerand outer ends, a central feed pipe, said feed pipe terminating abovethe inner edge of the bottom plate, channels lending therefrom andterminatiiig below said plates in'line with said orifices.

4. In a centrifugal milk se arator, in combination, a bowl, super osecplates therein provided with orifices t ierethrough between their innerand outer ends, a central" feed .provided with orifices t erethroughbetween nates, channels leading from said chamber and terminatingbelow'said plates, and in line with said orifices. 5

6. In a centrifugal milk separator, in combination a bowl, super osedplates therein J provided with orifices t ierethrough between theirinner and outerends, a central feed 1 ipe, a chamber, above the inneredge of the ottom late, in which said feed pipe term'i- I nates, cannels leading from said chamber and terminating line withsaid orifices,said channels having an open side.

7. In a centrifugal cream separator, in f combination, a bowl,superposed plates therein, provided with orifices therethrough, betweentheir innerand outer ends a central feed pipe, ribs projecting there mm,at 5 below said pla'tes and in as my invention,

' their inner and outer ends, a central feed I a point above the inneredge of the bottom pipe, a chamber above the inner edge of the plate,said. ribs being provided with channels bottom plate in which said feedpipe termiterminating below said plates and in line with said orifices.v 8. In a centrifugal cream combination, a bowl, superposed platestherein, provided with orifices therethrough, between their inner andouter edges, a central feed pipe, said feed pipe terminating above theinner edge of the bottom plate, projecting ribs from said feed pipe,said ribs bein provided With channels leading from sai feed p1pe,.andterminat ng below plates in line w th said orifices.
